No set hours as long as I am available at my core office hours. I don't see why cycling in would mean time is no longer an equation. Part of the commute equation is time of arrival. Otherwise it be leisure travel.

The elapse time of cycling will be longer due to having the need to first lock up my bike, walk into the office, drop my stuff, gather my change of clothes, walk over to the change room, perform body cleansing, put on office attire and walk back to my cubicle. This alone can add 10mins. If I shower it will be even longer.

As oppose to park the car, click the remote to lock up the car while walking to my office and plop myself into my chair. Actually one of my car self-locks after it detects me walking away with the key fob. So that err... saved 2 seconds of my time. And unlocks itself when I am within 4-5ft. And that new fandangled START button negates having to get the key into the steering column to start it too. Them lazy conveniences! What's next? automatically shift gears for me too?!
